In a move that surprised few industry watchers but signals a major strategic pivot, Ford has officially stepped into the grid-scale energy storage arena. The automaker created a new wholly owned subsidiary called Ford Energy, which will manufacture and sell large battery systems to utilities, data centers, and industrial customers. The subsidiary has a bold target: 20 GWh of annual production capacity from a repurposed Kentucky gigafactory. That number matters because the U.S. energy storage market is on track to grow by nearly 40% annually through 2030, and Ford wants a piece of that action. Here are three concrete ways the company plans to turn that 20 GWh ambition into reality.
How Ford Energy Plans to Deliver 20 GWh of Storage Per Year
Ford’s entry into stationary storage is not a side project. It is a deliberate reallocation of resources that were originally earmarked for electric vehicle batteries. The ford energy subsidiary inherits a massive manufacturing base, a team with deep battery expertise, and a product designed specifically for the utility-scale market. The plan revolves around three strategic pillars: reusing existing factory capacity, building a modular product platform, and betting on domestic supply chains to win contracts.
1. Repurposing the Kentucky Gigafactory for Storage Production
The single biggest advantage Ford has over other startups entering the energy storage market is its existing manufacturing infrastructure. The Glendale, Kentucky facility was originally constructed as part of the BlueOval SK joint venture with SK On. That joint venture dissolved in late 2024, and Ford took full ownership of the Kentucky operations. Instead of letting that capacity sit idle, the company is converting the plant into a dedicated energy storage gigafactory.
This is not a trivial retrofit. The facility was designed for high-volume EV battery cell production, which requires clean rooms, electrode coating lines, and formation equipment. Stationary storage cells, especially LFP prismatic cells, have different form factors and slightly different chemistry handling requirements. Ford has spent the better part of a year reconfiguring production lines, retooling assembly equipment, and retraining workers for the new product stream. The result is a plant that can produce 20 GWh of DC block units annually without building a single new structure from scratch.
The repurposing approach saves Ford billions of dollars compared to building a greenfield facility. It also compresses the timeline. The company expects first customer deliveries in late 2027, which is remarkably fast for a new entrant in the heavy industrial equipment space. That timeline is only feasible because the factory shell, the utility connections, the logistics infrastructure, and much of the workforce were already in place. The ford energy subsidiary essentially inherited a running start.
There is a subtle but important financial angle here too. By converting the plant from EV cells to stationary storage, Ford avoids writing down the billions already invested in the Kentucky site. That matters for the company’s balance sheet at a time when its EV division is still burning cash. The plant’s capacity is now redirected to a market where demand is outstripping supply, which improves the return on that original capital investment.
2. Designing a Standardized, Scalable Product: The DC Block
Having a factory is not enough. You need a product that can be manufactured at scale, installed quickly, and maintained reliably over two decades. Ford Energy’s answer is the DC block, a 20-foot containerized battery energy storage system that packs 5.45 MWh of rated energy into a single unit. The system uses 512 Ah LFP prismatic cells, which offer better thermal stability and longer cycle life than the nickel-manganese-cobalt chemistries commonly used in EVs.
The DC block comes in two variants. The FE-250 is optimized for two-hour discharge applications, typically used for peaker plant replacement or frequency regulation. The FE-450 is designed for four-hour discharge, which is the sweet spot for pairing with solar farms and providing evening ramping capacity. Both variants deliver the same 5.45 MWh energy capacity and operate across a voltage range of 1,040 to 1,500 VDC. That standardization is crucial for manufacturing efficiency. Ford can produce both configurations on the same assembly line with minimal changeover time, which helps hit that 20 GWh annual target.
The engineering details reveal a system built for real-world conditions. The DC block operates in temperatures from -35°C to +55°C, meaning it works in Canadian winters and Arizona summers without additional climate control. It carries IP55 ingress protection, which makes it resistant to dust and water jets. The C5 corrosion protection rating means it can handle coastal and industrial environments without rusting out after a few years. Each unit weighs about 43.5 tonnes, which is heavy but still transportable on standard flatbed trucks and container ships.
Ford also developed a proprietary battery management system and a liquid-cooled thermal management system. These are not off-the-shelf components. The BMS handles cell balancing, state-of-charge estimation, and safety monitoring across all 512 Ah cells. The liquid cooling keeps the cells within their optimal temperature window, which extends cycle life and maintains consistent performance over the system’s 20-year design life. When you multiply that by tens of thousands of units, even small improvements in cooling efficiency translate into significant long-term performance gains.
The DC block is designed to compete directly with Tesla’s Megapack, which currently dominates the U.S. utility-scale storage market. Tesla is expected to offer 5 MWh per Megapack 3 unit later this year and targets 50 GWh annual production capacity from its Houston gigafactory. Ford’s 20 GWh target is smaller, but the company believes its domestic manufacturing story and LFP chemistry give it a competitive edge with customers who prioritize supply chain security.
3. Betting on Domestic Manufacturing and Tax Credit Eligibility
The third piece of Ford’s 20 GWh strategy is arguably the most strategic: positioning the entire product line to qualify for U.S. federal tax incentives. The Inflation Reduction Act’s Section 48E Investment Tax Credit offers a base credit of 6% for energy storage projects, with a potential bonus of up to 5x that amount if the equipment meets domestic content requirements. To qualify for the full 30% credit, a certain percentage of the steel, iron, and manufactured components must be produced in the United States.
Ford is designing the DC block’s supply chain around those requirements. The cells are sourced from suppliers that meet U.S. free trade agreement criteria, which is complex for LFP cells given that China dominates that chemistry. The container structure, thermal management system, and power electronics are assembled at the Kentucky gigafactory. Ford has said it is actively working to increase the domestic content percentage as suppliers ramp up U.S. production capacity. If the company can hit the thresholds, customers who install Ford Energy systems will be able to claim the full 30% tax credit, which significantly improves project economics.

This domestic angle is not just about tax credits. It also addresses a growing concern among U.S. utilities and data center operators about reliance on Chinese-made batteries. The U.S. energy storage market is expected to add 24 GW of new capacity in 2026 alone, up from 15 GW in 2025. A significant portion of that capacity currently comes from Chinese manufacturers like CATL and BYD. Ford is positioning the ford energy subsidiary as a domestically assembled alternative that reduces geopolitical risk for mission-critical infrastructure.
Data centers are a particularly compelling segment. AI infrastructure buildout is driving unprecedented electricity demand growth. Hyperscalers like Amazon, Microsoft, and Google are signing power purchase agreements for gigawatts of renewable energy, and they need battery storage to smooth out the intermittency of solar and wind. Industry projections suggest data centers could account for 83% of behind-the-meter commercial and industrial storage deployments by 2030. Ford Energy is targeting those customers with a made-in-America message that resonates with their public sustainability commitments and their need for reliable, long-duration backup power.
What This Means for the Energy Storage Market
Ford entering the stationary storage business is a validation of the market’s growth trajectory. When a major automaker pivots a billion-dollar factory from EVs to grid batteries, it signals that the demand signal is strong and durable. Tesla deployed 46.7 GWh of energy storage in 2025 alone, a record that underscores how fast this market is scaling. The U.S. grid is projected to host over 600 GWh of battery storage by 2030, which means there is room for multiple large players.
Ford’s 20 GWh annual target represents roughly 3% of that projected 2030 market, assuming demand materializes as expected. That is a realistic share for a new entrant. The company is not trying to out-Tesla Tesla on volume. Instead, it is focusing on a specific value proposition: domestically assembled LFP storage systems that qualify for federal incentives and come from a manufacturer with decades of industrial-scale production experience.
The ford energy subsidiary also benefits from being a standalone entity with its own leadership. Lisa Drake, who was appointed president of Ford Energy in January, has a background in product development and manufacturing at Ford. Under her leadership, the team has spent close to a year securing supply chains, preparing the Kentucky site, and aligning the technology with customer requirements. That dedicated focus matters because energy storage customers have very different procurement cycles and technical specifications compared to automotive buyers.
Challenges Ahead
Ford’s plan is ambitious, but it is not without obstacles. The company needs to prove it can manufacture storage cells consistently at the required quality levels. LFP cell production is a different process from the NMC cells Ford’s suppliers traditionally made for EVs. Yield rates, defect rates, and cycle-life consistency all need to meet utility-grade standards, which are often more stringent than automotive standards for certain parameters like calendar life.
There is also the question of customer relationships. Ford has deep relationships with automakers, dealers, and fleet operators. It does not have established relationships with utility procurement teams, independent power producers, or data center developers. Building a sales channel, a service network, and a reputation in the energy industry takes time. The company has hired experienced energy storage executives, but trust and track record are built project by project.
Competition is another factor. Tesla is not the only incumbent. Fluence, Sungrow, BYD, and numerous other manufacturers have years of deployment experience and established supply chains. Ford’s domestic manufacturing angle is a differentiator, but competitors are also investing in U.S. production. A number of battery manufacturers have announced domestic cell production facilities in the last two years. The advantage Ford has is that its Kentucky gigafactory is already built and being converted, while many competitors are still constructing new plants.
